4 Rapid Customer Adoption of EqualLogic, iscsi and VMware Infrastructure 3 Sample of EqualLogic / VMware Customers Cost Effectiveness If you are looking for a full-featured, enterprise SAN without the high cost, take a look at EqualLogic. Performance / Scalability The EqualLogic products outperform any of the other SANs we have baked off. Ease of Use The EqualLogic units practically jump out of the box and mount/ configure themselves in your rack.

5 Business Needs for Disaster Recovery Minimize Downtime Minimize Risk Control Cost 93% of companies that lost their data center for ten days or more due to a disaster filed for bankruptcy within one year of the disaster. --National Archives and Records Administration 92% of users surveyed acknowledged that their companies would face serious consequences if they had to implement their disaster recovery plans. --Dynamic Markets Ltd. 73% of executives expressed concern with the costs associated with maintaining a secondary data centre --Beacon Technology Partners Effective disaster recovery is a business imperative, but is very difficult to achieve

6 Challenges of Traditional Recovery Slow Bare-metal recovery of OS Restore of data process Unreliable Dependencies on physical infrastructure Many manual and complex steps Testing is difficult and expensive Production Recovery Expensive Require identical infrastructure Recovery infrastructure mostly idle Cost of every change doubled

7 IT Best Practice Trend: Consolidation of Servers Mail Server DB Server Name Server Directory Server File Servers Backup Servers Application Servers Shares spare Logs spare Logs spare spare spare Stores Stores AD Domain More efficient resource utilization Reduction in licensing/hardware costs Fewer points of management Reduced physical footprint Lower power and cooling costs

8 VMware Virtualization Enablers for DR Hardware Independence Isolation App OS Batch Job App OS DR Test App OS VMware Infrastructure Run a virtual machine on any server without modification Encapsulation Each virtual machine is isolated from other virtual machines Partitioning System App Data s = files in VFMS Physical Server Turns servers into data % Utilization Safely run multiple virtual machines simultaneously on a single physical server

9 Server Consolidation Prerequisite: Consolidation of Storage Mail Server DB Server Name Server Directory Server File Servers Backup Servers Application Servers Shares spare EqualLogic iscsi SAN spare Logs Stores spare spare Logs spare Stores AD Domain Simplified provisioning Fewer points of management More efficient resource utilization Free Space RDM1 VMFS2 VMFS3 VMFS1 Backups Backups SQL RDM2 Higher availability Better backup and restore Improved data protection

10 Key Features Enabled by Networked Storage (SAN) VMotion Online migration of running virtual machines without interruption DRS - Distributed Resource Scheduling Optimizes resource usage based on current workloads VMware HA Automated rehosting and restart of virtual machine in case of server failure VMware Consolidated Backup Server-less backups

11 Why is iscsi Important? Reduces the Barrier to Networked Storage Uses more affordable hardware Extends existing infrastructure Leverages ubiquitous networking knowledge Helps simplify SAN deployments Enhances Consolidation ROI Reduces TCO for servers Lowers cost of VMware deployment Improves scaling of VMware infrastructure Servers Ethernet TCP/IP SCSI Packet Storage

12 Industry Trend: Virtual Servers Meet Virtual Storage Extendable, Scalable, and Resilient Infrastructure for Both Servers and Storage Path Virtualization Port Virtualization Capacity Virtualization

13 Key SAN Features for Data Protection and Recovery Redundant and Hot Swap Hardware Dual power supplies / dual fans Data copy facilities in SAN Hardware Snapshots Clones Replicas dual controllers LAN Hot swap drive carriers Backup Server Integration of SAN data copy with servers and applications Backup / Restore Quick Recovery Disaster protection and recovery Snapshots and t3 Clones t2 t1 Production Site SAN t4 t3 t2 t1 t4 Tape Library Remote Site r1 SAN r4 r3 r4 r2 r3 r2 r1 Replicas

14 Server-less Backup SAN Offloads Servers From Backup Tasks Step 1: Create a snapshot of the application volume Step 2: Backup server mounts the snapshot Step 3: Backup server copies the snapshot to tape Server Server Server LAN Backup Server 1 Gigabit Ethernet Fabric 3 EqualLogic PS Series Arrays Snapshot 2 Tape Library Remote Location

15 Recovery Process in a Virtualized Environment Example recovery process comparison 40+ hrs P-P Configure hardware Install OS Configure OS Install backup agent Start Single-step automatic recovery V-V Restore VM Power on VM < 4+ hrs RTO of a few hours, not days to weeks!

16 Customer Case Study Using VMware and EqualLogic LifeLink Foundation Challenges Need cost-effective disaster recovery for 7x24 access to critical organ donor databases Duplicating existing production environment at DR site too costly and complex Solution Virtualized environment based on EqualLogic SAN and ESX Server SAN-based replication of server images / data sets across 3 sites for quick disaster recovery Benefits Physical servers reduced from 12 to 2 Simple and cost effective disaster recovery IT environment SQL Server-based clinical and operational databases, Exchange, SharePoint, Citrix Traditional disaster recovery would have added much more complexity to our environment the EqualLogic/ VMware solution gave us DR along with simplicity.
